Description
Three times in the last two weeks, we've had our Jenkins server stop responding to requests. When I check syslog, I see errors like this:
Jun 30 16:07:18 jenkins [jenkins]: Jun 30, 2018 4:07:18 PM org.jenkinsci.plugins.workflow.support.concurrent.Timeout lambda$ping$0
Jun 30 16:07:18 jenkins [jenkins]: INFO: Running CpsFlowExecutionOwner[project/263:project #263] unresponsive for 5 sec

Jun 30 16:07:18 jenkins [jenkins]: INFO: Running CpsFlowExecutionOwner[project/318:project #318] unresponsive for 5 sec
These seem to persist indefinitely and there don't seem to be any other relevant messages in the log. The Web UI just hangs until nginx times out.
The Java process will then refuse to stop when I try to restart the service and I have to kill it with kill -9.
